Comparative Structural Analysis of Heavy Metal ATPases in Arabidopsis thaliana, Arabidopsis halleri, Brassica rapa, and Brassica juncea Полный текст
2022
Abdulrezzak Memon | Nuriye Meraklı
Arabidopsis thaliana has eight genes encoding members of the type P1B heavy metal–transporting ATPase, subfamily of the P-type ATPases. We focused our study on four ATPases, mainly HMA1, HMA2, HMA3, and HMA4, which are closely related and most similar in their sequences. We carried out the bioinformatics analysis of these metal ATPases and obtained their structure in A. thaliana, A. halleri, and the other heavy metal accumulators in Brassica spp. A. thaliana is a model plant for research because of the duplications and other evolutionary events. These evolutionary events provided a chance to elucidate their regulation and function in the cell. All previous bioinformatics analyses have given some information about their structure, but not much work has been done on their structural components and interactome analysis. Experimental determination of 3D structures is essential to understand better these proteins’ function, which is crucial for the proper functioning of all plant cellular processes. Especially, docking sites and domains need to be worked out to understand the role of these transporter proteins and their interaction in plant cells. These bioinformatic analyses will help the researcher understand these ATPases’ role in detoxifying the toxic metals from the cells of accumulator plants. Further research on gene cloning, gene expression, and generating new accumulator plants for phytoremediation is needed to reclamation polluted soils from toxic heavy metals.

In Turkey, three species of mulberries, white (M. Alba), black (M. Nigra), and red-purple (M. Rubra) are grown commonly. These widely can be consumed fresh as well as dry. However, its rapid post-harvest decay raises major concerns about the sustainability of the fruit for both food and economic purposes. In this regard, besides the fresh consumption of black mulberry fruit, it can consume as dried it also offers an alternative way. In this study, it was aimed to compare some quality parameters in fresh and dry samples of Morus rubra fruits grown in Tokat. It was applied different temperatures to Morus rubra fruits that at collected in two different maturity levels (semi-ripe and full-ripe). In the drying process, mulberry fruits were dried in a hot air dryer at 40, 50, 60, and 70°C. Total phenol, Total phenol, total monomeric anthocyanin, total antioxidant capacity, colour values (L, a, b) chroma, hue (ho), and browning indices values will be measured in fresh and dried products. In addition, different mathematical models will be tried by constantly noting the weight drops of the products at certain time intervals and determining which mathematical model will best predict the drying kinetics

Alper Zöngür | Naci Değerli
Six different temperate zone species of Cyprinidae family members, which are adapted to different harsh environmental conditions, were analyzed versus cold-acclimated Salmonid. Hemoglobin diversity in the studied species was investigated with a modified form of isoelectric pH: 3.5-10 ampholite system. 6 isohemoglobin bands were observed for cold-acclimated Oncorhynchus mykiss 8 isohemoglobin were observed for Chalcalburnus tarichi 9 for Cyprinion macrostomus and Sarkisla (Sivas) Cyprinus carpio, 11 Garra rufa and finally 12 for Todurge (Sivas) Cyprinus carpio. Cathodic/anodic ratios were found equal to 1for control and the fish adapted to available conditions. However, these ratios were found below 1 when environmental conditions were changed for fish, which are adapted to these poorly oxygenated conditions. Different environmentally adapted fish species are representing various isohemoglobins bands pattern. The species used as a control group in this study shown the lower isohemoglobin bands form. On the other hand, different forms of temperate climate Cyprinidae family member are produced isohemoglobins bands pattern, and the number of these band were higher than control group, depending on different adaptation conditions. The majority of these protein bands were anadic and it can be said that fish are producing anodic hemoglobin protein, when environmental conditions was changed to poorly oxygenated milieu.

2022
Atakan Koç | Berkay Gaser
Colostrum quality produced by dairy cows varies considerably. The amount of immune protein content in colostrum has also high specific gravity. In this study, the specific gravity of colostrum (SGC) produced by 32 Holstein-Friesian cows with different parities in the first five milking after calving, and additionally, the fat content (FC), non-fat dry matter content (NFDMC) and somatic cell count (SCC) in the milk samples taken in the first five milking and on the fifth and 10th day milking of lactation were determined. The effects of parity and milking order on SGC, FC, NFDMC and Log10SCC were detected to be statistically significant. Parity x milking order interaction effect was found to be significant for SGC, FC and NFDMC, but its effect on Log10SCC was insignificant. Cows with three and upper parities had higher SGC, FC, NFDMC, and Log10SCC than cows in the first and second parities. While SGC (1055.09±1.20 mg/mL), FC (6.36±0.12%) and NFDMC (18.17±0.37%) obtained at the first milking decreased gradually in advancing milking, Log10SCC (5.90±0.028) level increased. The correlation coefficients of SGC with FC, NFDMC, and Log10SCC were low-medium, the coefficients between FC and NFDMC were moderately too high in the first three milking, and decreased and approached zero in advancing milking. It was observed that SGC remained high even in the fourth milking in some cows, especially in the third and higher parities. In conclusion, it has been revealed that not only colostrum obtained from the first milking, but also quality colostrum produced in subsequent milking can be used in calf feeding in dairy cattle farms. However, all this depends on the adoption of the strategy of determining the quality of colostrum with the help of a colostrometer in dairy cattle farms.

Ageratum conyzoides is a widely spread weed, especially in the tropical and subtropical regions. It has been reported to be used as folk medicine in different countries for treating burns, wounds, skin disorders, headaches, fever, pneumonia, gynecological diseases, leprosy, snakebites, rheumatism, inflammations, stomach ailments like parasites, colic, diarrhea, dysentery, used as a painkiller during childbirth, and many more. It has been reported to contain active secondary metabolites such as alkaloids, tannins, phenols, saponins, coumarins, essential oils, and flavonoids, which support its medicinal uses in disease treatment and prevention. It can be a potential source of drugs for various diseases. In fact, pharmaceutical companies are being run in Brazil using A. conyzoides as raw material with recommendations from the Brazilian Drug Centre. It is also used for agricultural purposes as manure, insecticide, pesticide, herbicide, nematicide, fodder, etc. In China, it is widely intercropped in the citrus orchard to control pests and weeds. The review attempts to bring together medicinal and agricultural usage of Ageratum conyzoides with scientific evidence to demonstrate its efficacy. This weed has a negative influence in agriculture and the ecosystem but after studying about its potential medical and agricultural uses, we now have a different viewpoint on this weed, and we believe that further harnessing it for such positive uses might be a management strategy for this weed.

Selina Güngör | Betül Gürer
With this study, for guiding the policies on the protection of native animal genetic resources, the opinions of the sheep breeders about the national sheep and goat breeding program under farmer condition were evaluated within the scope of the purposes and needs of the breeders in Niğde province. The primary data was collected from 108 farms in Nigde Province Center and Bor districts, including 54 farms determined by the stratified sampling method from participated farms in the sheep breeding program and including 54 farms determined by the total population sampling method from not-participated farms in the sheep breeding program. As a result of the study, breeders stated that the main reasons for participating in the project were the ensuring both productivity increase by reducing the number of lamb deaths, and income increase by receiving the support from the project. Breeders stated that the project meets their expectations in a positive way. Approximately two-thirds of the farms not involved in the project were interested in the project, but the farms in this group were not able to participate in the project because they could not meet the project requirements mainly because they made animal production in small family farms by traditional methods. In addition, the study indicated that agricultural support programs to encourage participation in the breeding program were important for breeders. In this context, the support model for reducing costs was selected by breeders as the best criterion in a policy to be implemented for the protection of native animal genetic resources. It is recommended to expand the use of breeding material obtained from the project throughout the country. Besides it is recommended to expand programs in matters related to regular record keeping and animal care, feeding, herd management and health for small family farms.
